A boot loader authentication system has a multimedia device to be installed within a vehicle, a memory device, and a processor. The memory device stores data indicating a public key associated with the vehicle and a signed hash boot loader image indicating a signature of a private key. The processor is in communication with the memory device and is programmed to: generate a signature verification block based on a combination of a random number and a signed hash boot loader image; comparing the signature verification block with the public key to verify the signature of the private key; authenticating a boot loader in response to verifying the signature of the private key; and activating the multimedia device in response to boot loader authentication. 一种引导加载器认证系统，其具有要安装在车辆内的多媒体设备、存储器设备以及处理器。所述存储器设备存储数据，所述数据指示与所述车辆相关联的公钥以及指示私钥的签名的经签名哈希引导加载器映像。所述处理器与所述存储器设备通信并且被编程为：基于随机数与经签名哈希引导加载器映像的组合，生成签名验证块；将所述签名验证块与所述公钥进行比较以验证所述私钥的所述签名；响应于验证所述私钥的所述签名，认证引导加载器；以及响应于引导加载器认证，激活所述多媒体设备。
